| Abstract: |
| As the flattening and solidification behavior of the thermal sprayed particle impinged onto the flat substrate surface can be recognized as a fundamental phenomenon of the coating formation of the plasma spray process, a clarification of the flattening behavior of an individual particle is essential. In order to discuss the present status and development of flattening behavior research, the factors such as pre-heating temperature, spray ambient pressure, wetting ability, roughness of the substrate, solidification, desorption of adsorbates, which influenced the flattening behavior during the plasma spray process were introduced, and also the use of free falling experiment and numerical simulation method during the research work. Then gave a forecast of the development of the flattening behavior research, the numerical simulation model and experiments would be widely used to find the dominate factors during the flatting behavior, and answer the question why and how the disk splat appears on hot substrate and low pressure condition. |
